Abstract:
Theory of the resonant 3d → 2p X-ray emission spectroscopy (3d → 2p RXES) for insulating La compounds is presented; the incient photon is tuned to resonate with the 2p → 5d or continuum band (6s, 6d, …, εs, εd) transition and the X-ray emission due to the 3d → 2p transition is observed. The specra are calculated by using the impurity Anderson model and by applying the formula of a coherent second order optical process. We show that the Coulomb interaction between the electron photoexcited to 5d band and the system left behind plays an essentially important role in the spectra; this effect can be considered so-called post-collision-interaction (PCI). It is also shown that the gradual changeover from the adiabatic limit to the sudden excitations appears in the RXES when the incident photon energy increases from the near threshold to high energy continuum. Furthermore, because the RXES is sensitive to the 2p core hole potential, the ambiguity in the estimation of its strength left in a previous analysis of the XAS can be removed by the RXES.
